Livestream after-sales service: tool calls for operating reviews

Review tool calls for operating reviews in Livestream after-sales service. Check sources, input boundaries, error handling and repeatable test evidence.

What the documents look like

Livestream after-sales work clusters after a single session's traffic peak, and refund requests are strongly tied to what the host promised on air. Operating reports and exception reviews have to place the livestream order list, refund applications, reshipment orders and script templates into one checking chain. The role of tool calls and plugins at this step is to let the model decide, from a tool introduction and parameter introductions, whether to invoke a module or plugin, and to hand the result to the AI for a summary output. Data sources include the Douyin store after-sales system, customer service IM, the warehouse WMS and logistics tracking, with updates after each session and daily. Once these materials enter the workflow, which items are pending review and which already carry a signed or effective status must be distinguished item by item. Retrieval or a form collecting a value does not constitute authorized execution; business verification, approval, database writes and external synchronization each need their own downstream implementation.

Constraints at the tool calls step

A tool consists of a tool introduction and tool parameters. System module parameters are fixed; plugin parameters are configurable. Parameters carry two key values: the parameter introduction and whether the parameter is required. A tool with no parameters is judged directly from its introduction. With parameters but no required ones, the tool may be called even when no suitable parameter exists in the context, and the model sometimes fabricates a parameter. With required parameters and no suitable value, the model may not call the tool, and prompts can guide the user to supply the parameter. In advanced orchestration, dragging the tool call connection point makes a diamond appear at the head of available tools, which connects to the diamond at the bottom of the tool call module. A connected tool automatically separates tool input from ordinary input, and its introduction can be edited. A tool call termination node attached after a tool forcibly ends that call, invoking no further tools and no AI answer about the tool result. Custom variables extend tool input so that nodes not treated as tool parameters, or not callable as tools, can be invoked accordingly.

Hypothetical drill sample: the material text supplied for checking reads — a livestream order list marks "Order A-1001, refund application status is pending review, reshipment order not generated"; the customer service IM record states "the host promised seven-day no-reason return, script template version V3". A handover request to be judged reads: "Please call the reshipment plugin to generate a reshipment order for Order A-1001 and synchronize the warehouse WMS." In this request the refund application is pending review, no reshipment order exists, and no authorization boundary is stated. Pending review does not show an absence of operating permission, and it is not approval. Whether the reshipment plugin is called depends on the tool introduction, the parameter introductions and whether parameters are required, and on whether a suitable parameter exists in the context. Synchronizing the warehouse WMS is an external business action that needs a separate system implementation; the tool call itself does not complete it.

Configuration and implementation checks

Configuration itemHypothetical trial starting point for this pageChecking method
Tool introductionState the reshipment plugin's purpose, input conditions and situations where it should not be calledCompare against the plugin introduction text and check whether the pending review status is covered
Tool parametersList the parameter introduction and whether each is requiredFor Order A-1001, check whether a suitable parameter exists in the context
Required parametersWith no suitable value, the model may not call the toolObserve the actual request and record whether the model fabricates a parameter
Tool connectionIn advanced orchestration, connect a small number of tools before tuningCheck that the diamond connection and input separation take effect
Tool call terminationAttach after the reshipment plugin to end this callObserve whether further tools and the AI summary stop
Custom variablesFill in parameter descriptions for nodes that cannot be called as toolsCheck whether that node is invoked accordingly

These starting points are chosen for this hypothetical trial to compare against the plugin introduction text and the actual request; they are not official default values.

Three common errors

  1. Treating a retrieval or form-collected value as authorized execution. With Order A-1001's refund application pending review, calling the reshipment plugin and synchronizing the warehouse WMS conflates form collection with business approval and external synchronization. The input to check is the material text and the handover request; compare the pending review status against the authorization boundary; observe whether an unstated execution action appears.
  2. Treating a parameter introduction as a guarantee of execution. The parameter introduction only explains the parameter's meaning; only the required flag affects whether the model calls the tool. The input to check is the parameter introduction and the required field; compare whether a suitable parameter exists for Order A-1001 in the context; observe whether the model fabricates a parameter or declines to call.
  3. Treating tool call termination as an ordinary node. The termination node ends this call, invoking no further tools and no AI summary. The input to check is the connection position of the termination node; compare whether it sits after the reshipment plugin; observe whether subsequent tools and the AI summary stop.

How to verify the setup

  1. For the hypothetical sample text "Order A-1001, refund application status is pending review, reshipment order not generated", the input is the tool introduction and parameter introductions; compare the required fields against suitable parameters in the context; observe whether the model calls the reshipment plugin and whether it fabricates a parameter. The expectation is a decision governed by the introduction and parameter conditions, with no guarantee of a call or non-call.
  2. For the draft sentence "Please call the reshipment plugin to generate a reshipment order for Order A-1001 and synchronize the warehouse WMS", the input is the authorization boundary and the pending review status; compare whether business approval and external synchronization have downstream implementations; observe whether pending review is treated as approval. The expectation is that pending review remains unverified and that WMS synchronization requires a separate system implementation.
  3. For empty-result handling, the input is an explicit paper input []; compare whether the downstream design handles an empty result; observe whether any assertion appears that a fabricated rule's retrieval always returns []. The expectation is to record only what is observed and not to claim that an unrelated query must be empty.
  4. For cross-vector-model libraries, the input is the library identifier and the vector model identifier; compare whether they use the same vector model; observe whether non-matching ones are excluded and record the actual observation. The expectation is not to run cross-model retrieval to compare missed recalls, but only to check identifiers and exclude non-matching ones.
  5. For tool call termination, the input is the connection position of the termination node; compare whether it sits after the reshipment plugin; observe whether subsequent tools and the AI summary stop. The expectation is that this call ends as described in the documentation.
